Though I have not looked in ChipGuide, I feel that every known chip should be listed in ChipGuide whether there is an image of the chip or not.

It was like pulling teeth for me to get a poor, fuzzy image of chips listed where no other images existed or where the purchaser would not agree to submit a chip to the guide.

The cooperation I now have in submitting colors and shapes of chips where I can not obtain permission is excellent...

Good luck in finding the info you are looking for.
